Thousands of demonstrators have protested against Donald Trump's unexpected election as president in cities across the United States from Boston to Los Angeles.

The mostly peaceful protesters disrupted traffic, carried anti-Trump signs, and blasted the Republican real estate mogul on November 9 for his vow to deport millions of undocumented immigrants as well as statements and actions that have offended Muslims, women, and others.

The demonstrations came despite Trump's Democratic opponent, Hillary Clinton, who conceded defeat by saying the nation should give Trump a "chance to lead."

Clinton, who looks set to win the popular vote, conceded on November 9 that the election showed that "our nation is more deeply divided than we thought."

Trump will visit the White House on November 10 at the invitation of President Barack Obama.

In New York, thousands of protesters filled the streets of midtown Manhattan and made their way to Trump Tower, Trump's home on Fifth Avenue. Hundreds of others gathered at a Manhattan park and shouted, "Not my president."

In downtown Chicago, an estimated 1,800 people gathered outside the Trump International Hotel and Tower, chanting phrases like "No Trump! No KKK! No racist U.S.A."

In Boston, thousands of anti-Trump protesters streamed through downtown, chanting "Trump's a racist" and carrying signs that said "Impeach Trump" and "Abolish Electoral College."

In Seattle, police said they were responding to reports of a shooting with multiple victims near the scene of anti-Trump protests. Police said the shooting was unrelated to the demonstrations.

The protests were concentrated in coastal cities that voted overwhelmingly for Clinton, but also occurred in cities in the midwest and south like Richmond, Virginia; Omaha, Nebraska; and Kansas City.

In Austin, the Texas capital, about 400 people marched through the streets, police said.

Protesters railed against Trump's campaign pledge to build a wall along the border with Mexico to keep immigrants from entering the United States illegally.

Marchers chanted and carried signs in front of the Trump International Hotel in Washington, D.C. Another group stood outside the White House. They held candles, listened to speeches, and sang songs.

Protesters at American University in Washington burned U.S. flags on campus.

Hundreds also gathered in Philadelphia, Boston, and Portland, Oregon, and organizers said they were planning rallies in San Francisco, Los Angeles, and Oakland, California, on November 10.

Trump's campaign did not immediately respond. Trump said in his victory speech on November 9 that he would be president for all Americans. "It is time for us to come together as one united people," he said.

Earlier this month, his campaign rejected the support of a Ku Klux Klan newspaper and said that "Mr. Trump and his campaign denounces hate in any form."

Early on November 9, some 1,500 students and teachers rallied in the courtyard of Berkeley High School, and marched toward the campus of the University of California, Berkeley, a San Francisco area haven for liberals.

Hundreds of high school and college students also walked out in protest in Seattle, Phoenix, Los Angeles, and three other Bay Area cities -- Oakland, Richmond, and El Cerrito.

A predominantly Latino group of about 300 high-school students walked out of classes in Los Angeles and marched to the steps of City Hall, where they held a brief but boisterous rally.

Chanting in Spanish, "The people united will never be defeated," the group held signs with slogans such as "Not supporting racism, not my president" and "Immigrants make America great."

Many of those students were members of the "Dreamers" generation, children whose parents brought them into the United States illegally, and who fear deportation under a Trump administration, school officials said.

The demonstrations followed a night of protests in the San Francisco area and elsewhere in the country in response to Trump's victory against Clinton, who was heavily favored.

In the only major violence reported, demonstrators smashed storefront windows and set garbage and tires ablaze late on November 8 in downtown Oakland.
